I'd say mostly S&W (used on the bumper and grille to get all the bugs off while they're fresh), and to a lesser extent AW after about every other wash as a booster.
ONR for sure, not only for washing but for clay lube as well. Besides that, I'd say Poli-Seal, OCW, and OID are probably the products I use the most. I do a lot of one-steppers and then buff of PS with OCW. Then, wipe the vehicle down with OID.
